5 reasons to visit Cockatoo Island, Sydney

One of the more unusual places we visited while in Sydney recently was Cockatoo Island, a tiny island in the mouth of the Parramatta River.  If you haven’t spent much time in the city you may not have even heard of this little 18-hectare patch of land so I thought I’d share a few reasons you might be interested in taking a closer look.

Easy and inexpensive to get to

Unlike most of the islands in Sydney Harbour, Cockatoo Island is on a major ferry route making it both simple and quick to access.  It’s located a 10-minute ferry ride from Circular Quay if you get the direct ferry, some take a more scenic route via Darling Harbour and which takes 20 minutes.  The trip costs under $6 each way and the cruise offers exceptional views of the city coastline and harbour bridge as it passes.

We find the Sydney ferries a great way to see the city and use them frequently during our visits.  If you’re interested in getting around Sydney on public transport you might want to check out the linked article which examines the savings and convenience of using an Opal Card even if you’re only in the city for a short time.

Not far from the wharf when you arrive on the island is the information centre.  You can pick up brochures for the self-guided walking trails or learn a little about the layout and background of the island before heading off to explore.

A compact lesson in Australian History

Cockatoo Island isn’t the sort of small island you might normally imagine, it’s very different to our usual preference for an uncrowded natural space with hiking, snorkelling off secluded beaches and photographing wildlife. Places like Fitzroy Island in Tropical North Queensland or Savai’i in Samoa are usually our choice.  

This island is almost the complete opposite of what you would expect of an Australian Island. If it wasn’t for its sheer rock cliffs you could be forgiven for thinking it was fully man-made as it’s almost completely covered in concrete, structures and industrial equipment.  There’s a reason for that though and it’s what makes the island interesting.

Aboriginal History

You might also wonder how it came about the name of Cockatoo Island.  We didn’t see a single cockatoo (a noisy white Australian parrot) on the island but the name comes from the island’s earliest history before European settlement.  

It’s known that Aboriginals in the area didn’t live on the island as it had no freshwater but it’s thought the local Wangal people did camp and fish here prior to the arrival of European settlers and perhaps even used trees from the island to make their fishing boats.

Convict History

Between 1839 and 1869 Cockatoo Island operated as a convict penal settlement.  Looking at the remains today you can imagine that it must have made for a harsh living and working environment.  On the island are the remains of a number of the convict built structures including the prisoners’ hospital and barracks, a mess hall and underground silos.  Overcrowding in the colonial penal settlement reached critical levels and at one time 500 prisoners were living in a space not much larger than a modern house with barely enough room to lie down.

Cockatoo Island is one of eleven convict heritage sites in Australia that are listed in the UNESCO World Heritage Register as a place of special cultural and/or physical significance.  Despite having no interest in history whatsoever during my school years I do love to find and include these sites on our travels.

 Girls reformatory

In 1871 the island became an industrial school for girls.  In addition to being a reformatory for delinquents it was also home to orphans although the treatment and conditions for the two were not significantly different.  In 1888 it was closed and the girls were moved to Parramatta.

Wartime History

By the time of World War II, Cockatoo Island had become the primary repair facility for ships in the Southwest Pacific.  Around 250 ships were tended at the facility including the Queen Elizabeth and the Queen Mary.  The facilities were also used to convert merchant ships and passenger liners for the war effort.  Ships damaged in wartime attacks made it back the considerable distance to the island for repairs including the HMAS Australia after kamikaze attacks in the Philipines and the HMAS Hobart after torpedo attacks in the New Hebrides.

Its importance to the war efforts raised concerns about the potential for an enemy attack on the island and extensive bomb shelters was established in the tunnels beneath the sandstone hill in the centre of the island.

Maritime History

From 1857 until 1991 Cockatoo Island was Australia’s primary shipbuilding and repair facility with the yard handling over 12,000 dockings.  This history was a small part of our interest in visiting the island as Drew had spent some time on the HMAS Success while with the NZ Air Force.  HMAS Success was the last and largest naval ship ever built and launched from the island before the controversial decision to build Australian ships overseas.  There is an audiovisual display about its build in an annex to the dog-leg tunnel.

Viewing the island as a heritage site I was surprised to see that some boat industry continues on the island today although much smaller in size and scale.  Dry berthing, mooring and a full range of maintenance services for boats are still run commercially from the site.

The climb to the top of the hill is either via a road or very steep stairs straight up the cliff at the back of the island.  The harbour and cityside views alone are worth the climb.

Near the top of the stairs, this building is a rare example of a full-size Mould Loft built in 1911.  Full-scale templates of the steel portion of the ship’s hull were drawn out and cut here.  Everything was marked out in increasing levels of detail on the floor of the building and the marks can still be seen in parts today.  Although a huge space only half the ship could be templated at a time so naval cadets spent a good portion of their working week hunched and crouching.  Later in 1970 when technology allowed 1/10 scale templates to be converted and used the work continued on the upper level.

Other remnants of the time are the Sutherland dock built between 1882 and 1890 where larger ships and liners could be dry-docked.  The second photo is of beam benders a relic of the huge scale machinery used in the shipbuilding industry.

The Tunnels

There are three tunnels cut through the sandstone cliffs on the island.  The first was carved through in 1912 during the construction of the navy missile destroyer HMAS Brisbane.  It runs in a straight line from the southern docks to the shipyard.  At 113.3 metres long with its roof reinforced with tram rails, it was also used during WWII as an air-raid shelter.

The dog-leg tunnel entrance is near the information centre.  At 180 metres long it was created in 1915 to move workers and materials more efficiently around the island.   This also served as an air-raid shelter during the war and the various annexes served as storage and even an infirmary during that time.

The Cockatoo Island camping experience

There are several alternatives for accommodation on the island if an offshore stay is part of your Sydney wish list.  One of the more unique is to stay in one of the permanent tents in the camping ground right on the harbour edge.  It’s not a budget option but would be a memorable stay and the fire pit looked like a very inviting meeting place for swapping travel stories.

Camping on Cockatoo Island


And finally, you can’t leave the island without enjoying the million-dollar views while you relax with a coffee, meal or glass of wine.  The sparkling waters and Sydney’s harbour bridge from the outdoor cafe-style seating at Societe Overboard are something not to be missed on your visit and I highly recommend their chocolate chai.

If self-catering is more your thing there is also no shortage of picnic areas where you can enjoy similarly stunning outlooks if you prefer to bring along your own drinks and snacks.

Have you visited Cockatoo Island in Sydney?  Do you enjoy learning about the history and cultural background of places in your travels or does that bring back all too vivid memories of high school history lessons?

Unfortunately the visitor centre was closed the Friday we visited with no signage to indicate when it might open. We soldiered on alone and used google for our information source. When leaving the site 2.5 hours later we saw the VC was open. But alas we were turned away with "we're not open". When asking the attendant when the VC might actually be open we were met with "oh now don't be like that"??? My response? "Don't worry about it then" and we continued on to the wharf to leave. The idiot attendant followed after us telling us to go wait on the wharf (??) and "reported" us to the next dude at the Gate. What a disappointing end to what had been a terrific visit on a rainy wet day. Telling everyone about the ridiculous treatment and lack of friendliness, no information etc.

Hi Monica. It's disappointing to hear that but I am pleased you enjoyed your time on the island. The visitors centre is staffed by volunteers and officially open 9-5, we can only hope this was a one-off issue they experienced. Because of the hills, it is so helpful to have access to their help in picking the best route around the island to see everything you want to, especially for those with children or who find the walk more difficult. Thanks for letting me know, I'll see if I can go back and update our article to add a suggested walking route to take in the key points.

David and I stayed overnight there a few years ago - not in a tent but in one of the cottages. It was just fabulous after all the day visitors went home. We felt like we had the whole island to ourselves.

That sounds amazing Lyn, the idea of wandering it almost deserted is very appealing

I was hoping that you guys saw a cockatoo. I should have known it was all in the naming :) Interesting history there and it looks like a really interesting place that I had never even heard of.

It was OK Nataha, cockatoo are really common, we saw others that day in the city parks and we get them in the garden all the time, just not on the island.

I've never been to Australia but the more I read about it, the more I want to go. Sydney would be high on the list of this to see and now Cockatoo Island :). Beautiful photos BTW.
